'tain new and useful Improvements in Tlme- Cards; and I do herebydeclare the following to be a full,l clear, and exact descriptlon of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The present invention relates to an -1mproved time card for ascertainmgat a glance elapsed times between actual clock times punched thereon.This card may be used as a workmans time card, or to take records oftimes expended on jobs.

My im roved card is arranged with indications oi) successive clock'times on one side, and upon the other side a series of numbers areprinted directly behind the signs indicating clock times respectively,which numbers are so arranged that when two different signs indicatingclock times are punched, the corresponding numbers punched on thereverse side indicate by their dierence the elapsed time between theclock times. in question. By resorting to this expedient two importantadvantages are attained. First-the elapsed time between the beginningand end of a working period, for instance, may be ascertained instantlyby a simple subtraction. Secondthe sums of any number-or" periodsindicated upon separate cards may be rapidly ascertained by subtractingthe sum of all the smaller numers on the reverse sides of said cardsfrom the sum of all the higher numbers thereon. This is very useful inadding up total times spent on different days and by different men on acommon job.

A card arranged in a preferred manner with the above ends in view isshown in the accompanying drawings, wherein Figure l shows the obverseside of the card, and Fig. 2 shows the reverse side thereof.

For greater convenience and to Secure the quickest results and mostconvenient ar. rangement, I divide the day into hours and hoursthat isto say, into periods of six minutes each. In the particular form shown,each hour and its fractions occupy al horizontal row to themselves onthe obverse of the card and the noon hour is omitted. This arrangementis of course not a necessary one. The total number of time units (inthis case six minutes each) is indicated on the reverse by a successionof numerals from` one to the total (in this case 110).' Each numeral isplaced behind a correspending clock-time sign, so that, on punching anysign on the obverse side, a corresponding number in the series one to ahundred and ten is punched on the reverse side.

It is to be understood that, in stating that a number is punched, I donot restrict myself to the placing of a perforation so as v actually toremove a number, either on the front (obverse) or back (reverse) ot thecard. The placing of the punch mark so close to. either number punched(or to both) as to serve clearly to indicate what numbers are to be usedin 'computation is within my invention.

` I prefer to place the higher numbers near the top of the reverse face,as it is natural to subtract the lower from the higher number. This isnot essential.

The card shown is supposed to have been punched by a workman or by atime clock at. six minutes past seven when the workman came in, and atforty-eight/ minutes past live oclock, when he went out. Thecorresponding numbers on the reverse face are twelve and a hundred andnine, the difference being ninety-seven. Cates tenths of an hour, andtherefore it is only necessary to point off one decimal place in thisdifference to get the elapsed time in hours and tenths-namely nine andseventenths hours.

It will be observed `that, although the rows of -numbers read from leftto right on both sides of the card, the absolute or actual direction oiincreasing succession in the corresponding series is opposite on the twosides.

It is to be understood'that it is not essential to ymy broad inventionthat any particul'ar clock times be selected for printing, or that thoseselected should be printed in any particular order or arrangement. Thesuccessive time units may be equal or unequal without departing from thescope of my broadest claim; and, of course, it is not essential toselect tenths of an hour as the time unit. The total time interval maybe more or less than a working day.

In my claims I refer to vertical and horizontal lines or rows ofnumerals, but it is to be understood that these words are employed forconveniently distinguishing This indibetween the diferent seriesreferredto, and without intending to limit myself to the placing of the numeralsrepresenting hours, or instance, in a column perpendicular to the normalbottom of the card.I In otherv words, changingA the actual direction oflines of numerals with respect to the edges of the -card would notdepart from the intended scope of my claims.

What I claim is` v 1. A card having printed on its obverse -face in avertical line a 'series of numerals indicating successive hours and,opposite each numeral of the vertical row a horizontal row of numeralsdiferingsuccessively by a constant difference and in regular se-Vquental order as read across the card beginning at the vertical row,all the hori-l zontal rows consisting of the same numerals in the sameorder and havin on its lreverse -"face numerals printed behin thenumerals on the obverse face, said reverse numerals,

'forming a continuous series as read in horir zontal rows in thedirection opposite to the direction of progress of the corresponding?obverse rows, and the numerals of said re-=v verse series differingsuccessively by unity,

'fthe lowest numeral of the reverse series' being in horizontalalinement with the numeral indicating the latest hour in the obverse-vertical line, substantially j as de-v scribed. l

2. A card having printed on'its obverse 'face in a vertical line aseries of numerals indicating successive hours and opposite each numeralof the vertical row a horizontal row of nine numerals in regular se.- v

quent-ial order as readacross the card beginning at the Vertical row,'said' numerals indicating by their difference equal frac-1 tions of anhour; and having on its reversey face numerals printed behind thenumerals on the obverse face, said reverse numerals forming a seriescontinuously increasing by ,unity as read in horizontal rows in thediface in a vertical line a series of numerals indicating successivetimes, and oppositel each numerallof the vertical row a horizontal rowof numerals diiering successively.y

by a. constant difference and in regular sequential order as read acrossthe card beginning at the 'vertical row, all the horizontal Irowsconsisting of the same numerals in the Y sameorde'r and having on itsreverse facefr numerals printed behind Ithose on the obverse face andconstituting a group formed of horizontal rows so placed that there is aconstant difference between successive nu- "merals as readin successivehorizontale al-q Ways read in the same direction, said reversel numeralshavin such valueswith respect to their correspon ing obverse Anumeralsthat 'the difference between any two of them will indicate the elapsedperiod between the times indicated by the correspondin obverse numerals,substantially as described.

In testimony whereof, I affix my signa` ture, `in presence of twowitnesses.
